Limerick, Ireland, 6 October 2026
yieldHUB, the semiconductor yield management and real-time test floor intelligence company, today published a customer success story on Allegro MicroSystems. Allegro targeted a one-percentage-point improvement in overall equipment effectiveness (OEE) at its semiconductor manufacturing operation in the Philippines and gained several with yieldHUB Live.
Allegro was chasing utilization losses on its highest-volume test floor. yieldHUB Live, yieldHUB's real-time test floor intelligence software, went after the biggest one. The OEE result was achieved with no added test time, no new hardware and no test program changes.
"The impact on yield was kind of a revelation to us," said Eunice Esguerra, Section Manager, Final Test Product Engineering, Allegro MicroSystems Philippines. "We didn't really expect it to have that much of an impact in the first pass and also the final yields."
"When we eventually saw the dollar value, that was a happy surprise," Ms Esguerra added.
Allegro's own team is now rolling yieldHUB Live out across dozens more testers.
The full customer success story shows how Allegro turned its biggest utilization loss into higher first pass yield, recovered tester capacity and real savings. Download the Allegro MicroSystems customer success story.
